The Battle of Grünberg (21 March 1761) was fought between French and allied Prussian and Hanoverian troops in the Seven Years' War at village of Grünberg, Hesse, near Stangenrod. The French, led by the Jacques Philippe de Choiseul, inflicted a significant defeat on the allies, taking several thousand prisoners, and capturing 18 military standards. The allied loss prompted Duke Ferdinand of Brunswick to lift the siege of Cassel and retreat.
